Title: Improvements in mould presses having multi-part cavity moulds
IPC: B30B15/30
Filed: 1946-04-16
Abstract: 632,361. Opening moulds in compression moulding machines ; reciprocating moulds. WINGFOOT CORPORATION. April 16, 1946, No. 11741. Convention date, Oct. 10, 1945. [Class 87 (ii)] A multiple part mould, disposed between the platens 6, 7 of a press and hinged together at 14 and having moulding cavities formed between each pair of sections, is opened as the press platens 6, 7 move apart by a lever 22 hinged to the top mould section at 24 and connected by a pin and slot 27, 26 to the upper (fixed) platen 6. The initial rotation of the lever 22 as the lower platen 7 descends (the pin 27 travelling along the slot 26), causes the sections 11, 13 to be prised apart by a cam 33 on the end of the lever 22 bearing against an abutment 32 on the next lower section 13. When the pin 27 reaches the end of the slot 26 the lever 22 lifts the section 11 until a hook 29 pivoted thereon, having a handle 28, engages a member on the section 13 whereupon on further descent of the platen 7 the lever lifts both mould sections 11 and 13 away from the lowest section 12 which is held down on the platen 7 by two members 18 having flanges overhanging flanges on the section 12. Descent of the platen 7 is assisted by two plungers 39, bearing down on the platen and working in fluid tight cylinders 40 containing gas under pressure. As the platen 7 reaches its lowest position, a pin 42 on the plunger of a ram 19 engages a hole in a lug 43 on the mould section 12. Operation of the ram then slides the mould out of the press on rails carried by brackets 15, the sections 12 and 13 being widely separated by this movement. After unloading and reloading of the moulds in the section 12, the section 13 is unhooked from the section 11 (the weight being taken by a counterweight 34 to relieve the operator) and lowered onto the section 12 whereupon the mould in this section may be unloaded and loaded. Retraction of the ram 19 and operation of the press then causes the mould to close for the next moulding operation. The platens 6, 7 may be heated, e.g. by steam conduits therein or electrically. The Specification as open to inspection under Sect. 91 states that a two-part instead of a three-part mould may be employed, the intermediate part 13 and counter-balance being dispensed with. This subject-matter does not appear in the Specification as accepted.

Abstract: 688,398. Air space cables. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd. May 10, 1951 [May 16, 1950], No: 12242/50. Class 36. An electric conductor having air space insulation comprising a helical membrane is made by simultaneously moving the conductor and a tube of dielectric material thereon, which is in the form of a helix, and during said moving stretching the turns of the helix to the required pitch. The tubing M is cut into a helix and threaded in its unstretched form on to the conductor C which is supported by a trough 7. The conductor, with the helix thereon, passes through a clamp device 6 which retards the helix relative to the conductor and prevents rotation of the unstretched part of the helix. The conductor and partially stretched helix then pass through spacing head 5 which is provided with a revolvable disc 11 on which is mounted an arm 12 carrying a pair of rollers 13 between which the helical membrane passes so that its pitch is increased. The conductor with the spaced helix P thereon is then enclosed in dielectric or conductive tapes or in an extruded sheath. In an alternative method the-tubing M is applied to the conductor before being cut into the helix. Specification 608,147 is referred to.

Title: Improvements in and relating to the manufacture of organic nitrogen compounds
IPC: C07C205/40
Filed: 1942-09-02
Abstract: The reaction of ethylene with nitrogentetroxide, below the critical temperature of the latter, to produce 1 : 2-dinitroethane, b -nitroethanol and b -nitroethylnitrate is effected in the presence of oxygen.  In an example, a mixture of dry ethylene and oxygen is passed into liquid nitrogen tetroxide. The resulting mixture, is degassed by passing in air and is poured into methanol cooled with solid carbondioxide and methanol.  1 : 2-Dinitroethanol, thus precipitated is separated and the methanol removed from the remaining solution.  The resulting oil is treated with a mixture of benzene and water to separate the b -nitroethanol from the b -nitroethylnitrate. The latter is obtained from the benzene solution, and the aqueous solution is neutralised and extracted with ether to obtain the b -nitroethanol.  A mixture of oxygen with an inert gas, such as air may be employed instead of oxygen.  Specification 575,618 is referred to.

Abstract: 528,454. Sliding roofs for vehicles. BISHOP, W. H. April 26, 1939, No. 12476. [Class 108 (i)] A sliding roof of the type in which one end of the sliding panel is raised vertically by lever means in the closed position is now locked in any intermediate position by the same means co-operating with other members extending along the sides of the roof the rear edge of a panel 15, Figs. 2, 4 is guided at each side by a curved felt-covered slider 35 carried by a lug 36 pivotally mounted in a bracket 28. The slider travels between the base of a roof tray 11 and a lip 13 of a vertical flange 12 fixed to the tray and running parallel with the sides. When the roof is in the open position, Fig. 2, it can be locked by the operation of a handle 22 which causes arms 29 to move downwards against rubber-covered strips 39 on the base of the tray. The arms tend to force the roof upwards but it is held down by the sliders 35 under the lip 13. The operating rod to which the arms 29 are pivoted is light enough to hoist under excessive load so that if one arm engages before another the resilience of the rod will allow for this, the locking means preferably consist of cranked arms 29 on the outer end of rods rotatably mounted on the underside of the roof and engaging stationary longitudinal members 39 in the intermediate and 30 in the terminal position. The abutments 30 may be mounted to slide horizontally against spring action to avoid jamming. Specifications 463,749, and 531,004 are referred to.

Abstract: 418,150. Treating fibres ; yarns. COPLEY, J. F., Whinney Bank, Thongsbridge, near Huddersfield. May 1, 1933, No. 12575. [Class 120 (iii).] One or more rovings or slivers of cotton are twisted, two or more of such twisted rovings are doubled together, the resulting yarn then being mercerized, after which it is broken up or carded to yield loose fibres, or untwisted, drawn out and spun ; the degree of twisting and doubling being substantially as illustrated in the example below. The doubling is preferably effected by twisting in the reverse direction to that of the first twist, whereby the yarn can be more readily opened out. As an example of the degree of twist, two rovings each approximating to “ oz. per yard are twisted with 1¢ turns per inch, two such twisted rovings then being doubled in the reverse direction to give a two-fold yarn with a final twist of À6-À75 turns per inch.
